The effects of a self-developed virtual reality environment on college EFL learners’ vocabulary learning

ABSTRACT In second language acquisition (SLA), vocabulary learning can be a great challenge for some English as a Foreign Language (EFL) learners. Virtual Reality (VR) technology has unleashed its potential in language education, but insufficient attention has yet been paid to its impact on EFL learners’ vocabulary learning. To bridge this gap, we conducted a quasi-experiment based on a self-developed VR platform, in order to investigate the effects of VR on EFL learners’ vocabulary learning. A total of 68 college students participated in this study and were assigned to either the experimental (VR players) or the comparison (video watchers) group. The results revealed that the VR players significantly outperformed the video watchers in terms of vocabulary learning. The VR environment contextualized vocabulary learning by providing an authentic language learning experience, a strong sense of presence, and instant interaction and feedback, whereas the VR players’ learning motivation still needed to be strengthened. Analysis of semi-structured interviews further demonstrated that most of the students valued the potential of the VR-assisted learning approach, while some of them still held mixed feelings about it. This study provides some suggestions for both language instructors and technical experts in terms of task design, platform optimization, and material development.

Multi-user immersive environment for excavator teleoperation in construction

Excavation on jobsites is a collaborative effort, with a spotter serving as an extra set of eyes for the operator to ensure safety. However, current training methods using simulators are limited in immersion and primarily designed for individual operators to practice basic skills. This paper presents a multi-user teleoperation system featured with hybrid-immersive interface and between-user communication. The effectiveness of the system is evaluated through human subject experiments. The study's findings indicate that operators experienced greater immersion, a stronger sense of presence, and improved user interaction when using an immersive interface. This paper has important implications for the future of excavation training, with potential benefits including reduced utility strike damage and the opportunity to investigate human-robot collaboration in jobsites with multiple workers performing various roles within a highly immersive operational environment.

Developing an Interactive VR CAVE for Immersive Shared Gaming Experiences

The popularity of VR technology has led to the development of public VR setups in entertainment venues, museums, and exhibitions. Interactive VR CAVEs can create compelling gaming experiences for both players and the spectators, with a strong sense of presence and emotional engagement. This paper presents the design and development processes of a VR interactive environment called MobiCave (in room-scale size), that uses motion-tracking systems for an immersive experience. A user study was conducted in the MobiCave, aimed to gather feedback regarding their experience with a demo game. The study researched factors such as immersion, presence, flow, perceived usability, and motivation regarding players and the bystanders. Results showed promising findings for both fun and learning purposes while the experience was found highly immersive. This study suggests that interactive VR setups for public usage could be a motivating opportunity for creating new forms of social interaction and collaboration in gaming.

The Formation Mechanism of Impulse Buying in Short Video Scenario: Perspectives From Presence and Customer Inspiration.

It has been found in many cases that consumers are prone to exhibit impulsive buying behavior that is manifested as being immediate, emotional, and irresponsible especially under short video scenario. Supported by the customer inspiration theory, this study explores the psychological mechanism underlying impulse purchase in short videos that differentiates the traditional web shopping by the strong sense of presence in short video marketing. On the basis of a questionnaire survey and three laboratory experiments, this study examines the relationship among presence, customer inspiration, and impulse purchase intention. The empirical results point to the fact that social presence, co-presence, and physical presence have significant positive effects on impulse purchase intention, and customer inspiration mediates the effect of social presence, physical presence, and co-presence on impulse purchase intention. Furthermore, it is indicated that social and co-presence have stronger influences on impulse purchase intention than physical presence, thus proving a stronger effect of social factors on impulse purchase intention than physical factors in short video environment. The research results testify the impact of presence on consumer behavior in the upgrading short video marketing and provide valuable reference for marketing strategies to shorten consumers' decision-making time in short video purchase.

Effects of Roughness and Texture on Surface Material Perception in Virtual Environments: The Psychophysics Approach

Immersive virtual-reality computer-assembly serious game to enhance autonomous learning.

Immersive virtual reality (VR) environments create a very strong sense of presence and immersion. Nowadays, especially when student isolation and online autonomous learning is required, such sensations can provide higher satisfaction and learning rates than conventional teaching. However, up until the present, learning outcomes with VR tools have yet to prove their advantageous aspects over conventional teaching. The project presents a VR serious game for teaching concepts associated with computer hardware assembly. These concepts are often included in any undergraduate’s introduction to Computer Science. The learning outcomes are evaluated using a pre-test of previous knowledge, a satisfaction/usability test, and a post-test on knowledge acquisition, structured with questions on different knowledge areas. The results of the VR serious game are compared with another two learning methodologies adapted to online learning: (1) an online conventional lecture; and (2) playing the same serious game on a desktop PC. An extensive sample of students (n = 77) was formed for this purpose. The results showed the strong potential of VR serious games to improve student well-being during spells of confinement, due to higher learning satisfaction. Besides, ease of usability and the use of in-game tutorials are directly related with game-user satisfaction and performance. The main novelty of this research is related to academic performance. Although a very limited effect was noted for learning theoretical knowledge with the VR application in comparison with the other methodologies, this effect was significantly improved through visual knowledge, understanding and making connections between different concepts. It can therefore be concluded that the proposed VR serious game has the potential to increase student learning and therefore student satisfaction, by imparting a deeper understanding of the subject matter to students.Supplementary InformationThe online version contains supplementary material available at 10.1007/s10055-021-00607-1.

Exploring an Extended Conception of Grief: Sense of Presence and Grief Reactions in German Widows.

This study explores sense of presence (SOP) as an important feature of continuing bonds (CB) in the context of normal grief. A community sample of widows (N = 51) filled in a multidimensional grief questionnaire and a depression scale. A moderate positive association between sensing the deceased husband´s presence and cognitive and emotional impairments emerged. A positive relationship between SOP and guilt was found only if the influence of religiosity was controlled for statistically. There were no significant associations of SOP with long-lasting positive reactions to loss, such as personal growth and increase in sensitivity for others. Widows with clinically relevant depression indicated a stronger SOP than those with lower depression scores. These differentiated findings may stimulate the elaboration of an extended conception of grief beyond the focus on clinically relevant impairments.

Exploration on the Application of Internet Online Courses in Modern Teaching of Guzheng

As a traditional Chinese musical instrument, Guzheng wins favor from people since ancient times. In performance of Guzheng, its touching timbre and extensive everlasting rhyme create a strong sense of presence. Nowadays, since internet technologies have become the infrastructure in modern society, the paper studies how to achieve in-depth fusion of teaching of Guzheng (a representative of traditional culture) and the emerging internet technologies. In this paper, the advantages of introducing internet online courses into modern teaching of Guzheng are summarized, followed by a tentative analysis of application of internet online courses in modern teaching of Guzheng.

Fear and loathing in VR: the emotional and physiological effects of immersive games

Compared to traditional screen-based media, virtual reality (VR) generally leads to stronger feelings of presence. The current study aimed to investigate whether playing games in VR resulted in a stronger sense of presence than playing on a TV, and whether these feelings of presence affected players’ emotional and physiological responses to the games. Two experiments were conducted among 128 students, comparing the effects of playing either a survival horror game (N = 59) or a first-person shooter (N = 69) on a TV or in VR on physiological and subjective fear, hostility and enjoyment. Results showed that playing games in VR resulted in a stronger sense of presence, lower heart rate variability and a stronger subjective sense of fear. The feeling of presence thereby mediated the effects of VR on fear. The effects of playing a first-person shooter in VR on hostility were mixed, and gaming in VR was not more enjoyable than on TV. Regardless of the type of game or display medium, hostility increased significantly post-play. This study provides evidence that commercial VR games can affect feelings of presence and the physiological and emotional state of players.

Estimating Angular Resolutions Required in Light-Field Broadcasting

Light-field technology has significant potential for future three-dimensional (3-D) television (TV) services in which 3-D objects or spaces are shown with a strong sense of presence. However, the physical specifications required for light-field displays to show the typical scenes depicted in current broadcasting are not yet known. In particular, angular resolution is a representative specification that describes the image quality related to the depth reconstruction; we investigated the angular resolutions required for providing future 3-D TV services assuming the display of substantially deep scenes and multiple viewing positions in typical viewing environments with small-, medium-, and large-sized displays. We made every effort to minimize the requirements on the display specifications for presenting 3-D scenes with substantial depth by using `depth compression expressions' that manipulate the scene geometry so that viewers do not feel that the scenes appear unnatural. We conducted subjective evaluation experiments on the simulated views on the light-field displays with various angular resolution settings. As a result, we found that the required angular resolutions depended on the viewing environment and were 0.51, 11.2, and 12.1 views per degree in the small-, medium-, and large-sized display environments, respectively. We also obtained pixel-pitch and micro-lens specifications that would present the estimated angular resolutions on a light-field display and developed a design goal for future display-device development.

An integrated emotional and physiological assessment for VR-based active shooter incident experiments

Unfortunately, active shooter incidents are on the rise in the United States. With the recent technological advancements, virtual reality (VR) experiments could serve as an effective method to prepare civilians and law enforcement personnel for such scenarios. However, for VR experiments to be effective for active shooter training and research, such experiments must be able to evoke emotional and physiological responses as live active shooter drills and events do. The objective of this study is thus to test the effectiveness of an active shooter VR experiment on emotional and physiological responses. Additionally, we consider different locomotion techniques (i.e., walk-in-place and controller) and explore their impact on users’ sense of presence. The results suggest that the VR active shooter experiment in this study can induce emotional arousal and increase heart rate of the participants immersed in the virtual environment. Furthermore, compared to the controller, the walk-in-place technique resulted in a higher emotional arousal in terms of negative emotions and a stronger sense of presence. The study presents a foundation for future active shooter experiments as it supports the ecological validity using VR for active shooter incident related work for the purposes of training or research.

Affective three-dimensional brain–computer interface created using a prism array-based display

To avoid the vergence-accommodation mismatch and provide a strong sense of presence to users, we applied a prism array-based display when presenting three-dimensional (3-D) objects. Emotional pictures were used as visual stimuli to increase the signal-to-noise ratios of steady-state visually evoked potentials (SSVEPs) because involuntarily motivated selective attention by affective mechanisms can enhance SSVEP amplitudes, thus producing increased interaction efficiency. Ten male and nine female participants voluntarily participated in our experiments. Participants were asked to control objects under three viewing conditions: two-dimension (2-D), stereoscopic 3-D, and prism. The participants performed each condition in a counter-balanced order. One-way repeated measures analysis of variance showed significant increases in the positive predictive values in the prism condition compared to the 2-D and 3-D conditions. Participants’ subjective ratings of realness and engagement were also significantly greater in the prism condition than in the 2-D and 3-D conditions, while the ratings for visual fatigue were significantly reduced in the prism condition than in the 3-D condition. The proposed methods are expected to enhance the sense of reality in 3-D space without causing critical visual fatigue. In addition, people who are especially susceptible to stereoscopic 3-D may be able to use the affective brain–computer interface.

Transformation of flow in rehabilitation: The role of advanced communication technologies

Authentic rehabilitation requires the active participation of patients and their involvement with opportunities for action and development. Within this framework, in this article we outline the possibility of using two emerging computing and communication technologies-ambient intelligence (AmI) and virtual reality (VR)--for a new breed of rehabilitative and clinical applications based on a strategy defined as transformation of flow. Transformation of flow is a person's ability to exploit an optimal (flow) experience to identify and use new and unexpected psychological resources as sources of involvement. We identify the feeling of presence--the feeling of being in a world that exists outside oneself--as the theoretical link between the technology and rehabilitation. AmI and VR are used to trigger broad empowerment processes induced by a strong sense of presence, leading to greater agency and control over one's actions and environment.

An investigation into alleged 'hauntings'.

In cases of alleged hauntings, a large number of seemingly trustworthy witnesses consistently report experiencing unusual phenomena (e.g. apparitions, sudden changes in temperature, a strong sense of presence) in certain locations. The two studies reported here explored the psychological mechanisms that underlie this apparent evidence of 'ghostly' activity. The experiments took place at two locations that have a considerable reputation for being haunted-Hampton Court Palace (Surrey, England) and the South Bridge Vaults (Edinburgh, Scotland). Both studies involved participants walking around these locations and reporting where they experienced unusual phenomena. Results revealed significantly more reports of unusual experiences in areas that had a reputation for being haunted. This effect was not related to participants' prior knowledge about the reputation of these areas. However, the location of participants' experiences correlated significantly with various environmental factors, including, for example, the variance of local magnetic fields and lighting levels. These findings strongly suggest that alleged hauntings may not necessarily represent evidence for 'ghostly' activity, but could be, at least in part, the result of people responding to 'normal' factors in their surroundings.
